Change Enspells to be based on Delay and Enhancing Magic (like Sambas)
2-handed weapon users only get half the DoT from Enspells that 1-handers get. Change this, nao! If you swing half as frequently, maybe you get 50% higher enspell damage?
Rare/Ex item that calls your chocobo to a party member to ride it.
There's items that are usable only on party members (reraise on them, etc). Add one as a reward to Chocobo Racing/Raising/Whatever that let's you call your chocobo to let a friend ride it once a week or so maybe? (Or for that retarded guy who doesn't bring Sneak/Invis to parties on Puks.)
Add an Enchantment on Guttler that calls a Greater Bird pet.
BSTs seriously need to have a giant bird show up and follow them around for an hour or so once a day if they go through the effort of obtaining a Guttler. If only to comfort them for wasting all that currency.
Auto-QM'ing of drops to a BCNM Orb holder.
Sometimes it is hard to find non-theives to do BCNM/KSNMs with. This would remedy that.
Automatic /Recast on spells like JAs.
If you try to use a Job Ability that isn't ready, you get a "0:31" or whatever left on it. Automatically in the log window. Why can't spells do that without taking up a macro line with /recast?
Ninja gets a Catch ability like in FFT.
SE seemed to have some idea of making Ninjas into ranged attackers/debuffers or something. Give a Lv. 37+ Job Trait or JA that let's them occassionally catch projectiles fired at them instead of auto-eating a shadow.
